What Is Copper Powder?

Main uses: Widely used in powder metallurgy, electric carbon products, electronic materials, metal coatings, chemical catalysts, filters, heat pipes and other electromechanical parts and electronic aviation fields.

Copper powder first aid measures

Skin contact: Remove contaminated clothing and rinse with plenty of running water.

Eye contact: Raise eyelids and rinse with running water or saline. Seek medical attention.

Inhalation: Quickly leave the scene to fresh air. If breathing is difficult, give oxygen. Seek medical attention.

Ingestion: Drink plenty of warm water and induce vomiting. Seek medical attention.

Copper powder fire protection measures

Dangerous characteristics: Its powder can burn when exposed to high temperature and open flame.

Hazardous combustion products: Copper oxide.

Extinguishing method: Move the container from the fire field to the open area as far as possible. Fire extinguishing agent: dry powder, sand.

Copper powder emergency treatment

Emergency treatment: Isolate leaking contaminated areas and restrict access. Cut off the fire. It is recommended that emergency handlers wear dust masks (full face masks) and general work clothes. Collect with a clean shovel in a dry, clean, covered container. If there is a large amount of leakage, collect and recycle.

Part VII: Handling and Storage

Precautions for operation: The operators must be specially trained and strictly abide by the operating regulations. It is recommended that operators wear self-priming filter dust masks and chemical safety protective glasses. Away from fire and heat sources, smoking is strictly prohibited in the workplace. Use explosion-proof ventilation systems and equipment. Avoid contact with oxidants, acids and halogens. Handle lightly during handling to prevent damage to the packaging. Equipped with the corresponding variety and quantity of fire fighting equipment and leakage emergency treatment equipment. Empty containers may be harmful residues.

Storage precautions: Store in a cool, ventilated warehouse. Keep away from fire and heat sources. It should be stored separately from oxidants, acids and halogens. Equipped with the appropriate variety and quantity of fire equipment. The storage area should be equipped with suitable materials to contain spills.

Copper powder personal protection

Occupational exposure limit

China MAC (mg / m3): 1 [dust], 0.2 [smoke]

Former Soviet Union MAC (mg / m3): 0.5 1

TLVTN: smoke 0.2mg / m3 dust and mist 1mg / m3 (based on copper)

TLVWN: No standard set

Engineering control: Generally no special protection is required.

Respiratory protection: Generally, no special protection is needed, but when it may be exposed to dust, it is recommended to wear a self-priming filter dust mask.

Eye protection: Generally, no special protection is required, but it is recommended to wear chemical safety protective glasses in special cases.

Body protection: Wear general protective clothing.

Hand protection: Wear general work protective gloves.

Disposal of copper powder

Disposal methods: If possible, recycle. If recovery is difficult, copper can be precipitated by adding alkali solution and then landfilled.

Copper powder shipping information

Precautions for transportation: The package should be complete at the time of shipment, and the loading should be secure. During transportation, ensure that the container does not leak, collapse, fall, or damage. Do not mix and transport with oxidants, acids, halogens, etc. During transportation, it should be protected from direct sunlight, rain and high temperature.
